Big expansion and renovation projects are coming to Ascension Health's St. John Macomb-Oakland Hospital in Warren and Providence-Providence Park Hospital in Southfield, including dozens of new private rooms.

A $48-million expansion to St. John Macomb-Oakland is to start in November and grow the hospital's east tower to seven floors from its current four. The project will add just 15 new beds, but create 75 new private rooms and renovate 42 of the hospital's existing private rooms. When the project is done in summer 2019, the hospital will have 375 total beds, 220 of them in private rooms.

"Private rooms are an expectation for a lot of patients," hospital spokesman Brian Taylor said Thursday. "A lot of patients don't want to share rooms."

Taylor said the hospital will not charge patients or insurance more for the new private rooms than it does for traditional double rooms.

St. John Macomb-Oakland has launched a $2-million fund-raising campaign to help finance the expansion.

A three-year, $15-million renovation is to begin this fall at Providence-Providence Park Hospital in Southfield. This project will upgrade critical care units, surgical areas and the birthing center. It also includes new interior decorating and upgrades to patient rooms and nursing stations.

"The renovations at Providence Hospital and the addition of more private rooms at St. John Macomb-Oakland will improve efficiency and safety, as well as provide a more pleasing environment for healing for patients and families," Gwen MacKenzie, Ascension Health's senior vice president and market executive for Michigan, said in a statement.
